VICTOR E. COHEN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE \VONDERFUL BURNER COMPANY, OF SAME PLACE.

ATTACHMENT FOR INCREASING THE ILLUMINATING POWER OF GAS-JETS.

SPECIFICATION forming part of Letters Patent No. 427,050, dated May 6, 1890.

Application filed July 11, 1889. Serial No. 317,169. (No model.)

To all whom it mag concern.-

Be it known that I, VICTOR E. COHEN, of

Philadelphia, in the State of Pennsylvania,

manufacture, and more efficient in operation than has hitherto been the case.

In the accompanying drawings, Figure 1 represents an ordinary gas-jet having my improvements applied thereto, the deflectorplate being thrown out of operation. Fig. 2 is a similar view of the plate in operation. Fig. 3 is a top view of the jet, showing the position of the deflector-plate when in operation. Fig. 4 is a perspective view of the entire attachment removed from the burner; and Fig. 5 is a partial view of the lower end of said attachment, showing details which will afterward be described.

In said drawings, A represents the gas-jet, upon the side of which the attachment is to be supported. The support consists, preferably, of a pair of split or open ringsB B, connected by a strip 0, upon whose other side is a pair of holding and guiding clips F F. This piece may be conveniently stamped from a fiat piece of sheet metal.

E represents the deflector-plate, which is mounted upon an arc-shaped stem D, embraced by but sliding freely within the clips F F. In the lower of the two rings B, I form immediately adjacent to the stem D a small spring-stop G. (See Fig. 5.) The deflectorplate E is convex on the side next the flame, and is preferably oval in shape, as shown, so that when in its lowest position (see Fig. 2) it shall properly overhang the issuing current and modify the flame II, as before stated. When the plate is to be thrown out of play, it is raised up by sliding the stem D upward in the clips F F until the curvature of said stem throws the plate backward clear of the fiam e. IVhen in this position, the stem is firmly held up by means of the spring-stop G, so that it cannot be jarred or slipped downward. WVhen,

however, it is depressed by hand, said spring G bears lightly against the inside of the stem D and overcomes the play which it is desirable to leave in the holding-clips F F, thus bearing the deflector-plate E firmly up against the tip of the burner in a proper position to insure the best results.

I do not claim, broadly, the use of a movable deflector-plate in connection with a gasburner, nor do I limit my claim to the use of a pair of open rings as a means of mounting the device upon the jet; but,

Having thus described my invention, I claim- 1. The combination, with a supporting-piece adapted to be mounted upon a gas-jet,'of an arc-shaped stem sliding in suitable guides upon said support, and a deflector-plate car ried by said stem, substantially as set forth.

2. The combination, with a supporting-piece adapted to be mounted upon a gas-j et, and with an arc-shaped plate-carrying stem sliding in suitable guides thereon, of a stop upon said supporting-piece, said stop engaging with said sliding stem, both in a raised and lowered position, and a deflector-plate carried by said stem, substantially as and for the purposes set VICTOR E. COHEN.

forth.
